Phenotypic/genotypic sex mismatches and temperature-dependent sex determination in a wild population of an Old World atherinid, the cobaltcap silverside Hypoatherina tsurugae.

Abstract excerpt

Several New World atheriniforms have been recognized as temperature-dependent sex determined (TSD) and yet possess a genotypic sex determinant (amhy) which is primarily functional at mid-range temperatures. In contrast, little is known about the sex determination in Old World atheriniforms, even though such knowledge is crucial to understand the evolution of sex determination mechanisms in fishes and to model the...
